There were a total of 11 losses last week by Top 25 teams, including No. 25 Wyoming, No. 2 Michigan and No. 1 Duke all suffering their first losses of the season. Duke and Michigan, it should be noted, lost road games to ranked teams -- North Carolina State and Ohio State.
Last week's No. 3 Arizona was among those teams losing and that allows Louisville (15-1) to jump from fourth to No. 1. The Cardinals are the third team -- after Indiana and Duke -- to be ranked on top of the poll this season. They were given 18 of the 31 first-place votes.
Indiana (15-1) goes from fifth to second and picked up six first-place votes. Duke (15-1) drops two places to third but is still first on seven coaches' ballots.
Kansas (14-1) takes the fourth spot, after being sixth for three weeks. Michigan (16-1) drops to fifth and Syracuse (16-1) is up one place to sixth. Arizona (15-1) is down four to No. 7 while No. 8 Gonzaga (16-1) and Florida (12-2) are again eighth and ninth, respectively. They are the only Top 25 teams to hold the same position as last week.
Creighton (16-1) re-enters the Top 10 at 10th and Ohio State (13-3) comes in No. 11, up three from a week ago. Minnesota (15-2) slips two to 12th but Butler (14-2) is up four to 13th, San Diego State improves one place to No. 14 and North Carolina State gains six spots to No. 15.
Missouri (12-3) falls four places to 16th, ahead of No. 17 Michigan State. Kansas State (13-2) is 18th and Virginia Commonwealth (14-3) is No. 19 after both vault five places in a week. Notre Dame (14-2), 16th a week ago, is 20th.
New Mexico (14-2) is again ranked, coming in at 21st but Illinois (14-4) after an 0-2 week plummets nine places to 21st. Nevada-Las Vegas (14-3) and Cincinnati (14-3) both fall four places to 23rd and 24th, respectively, after losses last week. UCLA (14-3), which fell out of the ranking Dec. 3, is 25th.
Georgetown and Wyoming drop out of the Top 25 this week.
